﻿The multiplicative property of triangular Toeplitz matrices is used to derive a polyproduct rule for companion matrices. This rule is then used to obtain some new identities involving resultants and companion matrices, and to investigat...

﻿An analysis of a simply supported rectangular elastic plate forced into bending vibrations by the application of time harmonic voltages to piezoelectric actuators attached to its bottom and top surfaces is performed by using the equatio...

﻿We prove that in the finite field F=FqF=Fq, q=2mq=2m, with a primitive element αα, there exists a nonzero element ββ such that
maxt∈[0,1)∑k=0q-2(-1)Tr(βαk)e2πikt1π2qlnlnq.As an application of this result we show that the ...

﻿The occurrence of a congenital midline sinus of the upper lip is rare, only 22 cases having been previously reported. This case report describes the excision of a congenital midline sinus of the upper lip in a 2-year-old girl.
The foll...

﻿We discuss an elementary method of proving that certain smooth differential equations Air Jordan Retro 1 Canada exhibit a kind of chaos. In some cases, such as a forced pendulum, the proof is simpler than an approach through Poincaré m...

﻿We consider weighted graphs, where the edge weights are positive definite matrices. In this paper, we obtain two upper bounds on the spectral radius of the Laplacian matrix of weighted graphs and characterize graphs for which the bounds...

﻿A machine has been developed for handling “internal” targets Cheap Air Jordans Online from the 60-inch cyclotron by remote control in a lead-shielded box. The machine is regularly used to shave active materials from metallic targets...

﻿This article describes the results of a survey of seven academic disciplines. The survey showed that all respondents, regardless of academic discipline, consult a narrower range of materials than was expected and regularly consult older...

﻿A gauge- and Lorentz-invariant semiclassical state is constructed for the SU(2) gauge theory. It is stable at the one-loop level and has lower energy density than the famous ferromagnetic state. The expected local vacuum properties are ...

﻿In this paper the existence of mild solutions of a class of semilinear stochastic evolution inclusions with delays in a Hilbert space is studied. The results are obtained by using a fixed point theorem for condensing map due to Martelli...
